Title:
A DRY DISCONNECT COUPLING VALVE
Document Type and Number:
WIPO Patent Application WO/2015/107120
Kind Code:
A3
Abstract:
A coupling valve (1) has two parts (2, 3) each having a fluid conduit (5, 21) and a valve closure disc (6, 8). The discs (6, 8) are on shafts (7, 9), each being at is 45° to its respective shaft. The valve discs (6, 8) and their shafts (7, 9) are lined, as are all fluid-contacting surfaces. The discs (6, 8) are configured to press together when the parts (2, 3) are coupled and to move together between closed and open valve positions. The movement is by rotation of one (7) of the shafts as a master shaft, drive being transferred to the other disc (8) by virtue of a friction fit under a compression load applied by a coupling mechanism (15). An O-ring (60) assists the dry seal between the valve discs (6, 8).
